refrigerator

Abstract

The invention discloses a refrigerator, comprising: a box body, the box body has a refrigeration compartment; a door body, the door body is arranged on the box body to open or close the refrigeration compartment; and an air duct assembly, the air duct assembly is arranged in the refrigeration room Indoor, and the air channel assembly and the box define the air supply channel for supplying air to the cooling room and the return air channel for exhausting the cooling room, and the return air port of the return air channel is located in the cooling room bottom of. According to the refrigerator of the present invention, by rationally setting the air supply duct and the return air duct, the cooling capacity in the refrigeration room is distributed more evenly, the cooling effect is effectively improved, and the loss of energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a refrigerator. Background technique [0002] The refrigeration process of the air-cooled refrigerator in the related art is as follows: the evaporator acts in its pipeline, and the surface emits cold energy. The fan motor on the air duct drives the fan blades to rotate, and the cold energy is sent to the air duct. The air outlet, the cold energy flows out from the air outlet and is distributed to the corresponding area in the box. Finally, the cold energy is returned to the surface of the evaporator through the air return port on the air duct, and the cycle is repeated so that the temperature field in the box tends to be uniform. So as to achieve the cooling effect. [0003] Refrigerator compressors are mostly installed at the lower rear of the refrigerator. For air-cooled refrigerators, the upper edge of the lower drawer in the freezer is often at the same height as the ...

AI Technical Summary

Problems solved by technology

[0003] Refrigerator compressors are mostly installed at the lower rear of the refrigerator. For air-cooled refrigerators, the upper edge of the lower drawer in the freezer is often at the same height as the return air outlet, and most of the cold energy will enter the return air outlet along the upper edge of the lower drawer. Complete the cooling cycle, which will cause insufficient cooling in the lower drawer, and the temperature will be higher than other corners of the refrigeration room. Therefore, only by extending the running time of the compressor can the requirement be met, but if the compressor runs for a long time, it will cause The other corners of the refrigeration room will be too cold, and the energy consumption will increase. At the same time, most of the air-cooled refrigerators will have condensation on the top and the door liner, and more seriously, the condensation will cause freezing
